I’m not saying he would necessarily have an easier time travelling if he were to look just like everyone else, but it probably wouldn’t hurt.

I am attaching a picture of Mr. Snowden to this post. However, your likeness doesn’t need to be perfect — apparently Bolivian President Evo Morales was considered to have a pretty good resemblance, by the people who caused his plane to be intercepted. (Oh, the mistakes we could all avoid if people would just bother to learn a little Spanish.)

Honestly, I think the two look pretty different. Make sure the costume shop gives you the right mask.
